Hi,

I have this error on a 'Disk Free' sensor, Target Dell laptop windows 7. The error specifies q: drive, but I dont have a q: drive? I ran the WMI tester and query which accesses my c: drive fine. The query used and results are posted below. Does anybody know how to resolves this?

Last Message: The host's WMI system is returning invalid data: in class Win32_LogicalDisk - q: FreeSpace q: Size To resolve this issue, use Paessler WMI Tester (https://www.paessler.com/tools/wmitester) with the correct query from https://kb.paessler.com/en/topic/8783 to test the accessibility of your WMI counters. (code: PE098)

query used in WMI Tester -

SELECT DriveType,DeviceID,FreeSpace,Size,VolumeName
FROM Win32_LogicalDisk
WHERE DriveType=3

WMI Tester results -

Hello,
The Q drive on a Dell Laptop is usually tied to a Office Click-To-Run Installation as described at Dell here: https://www.dell.com/community/Productivity-Software/Local-disk-Q-MS-office-2010/td-p/3637275

It can be hidden in Explorer by default but might still be picked up using WMI.
You can also use the Disk Management Console Snap-In (diskmgmt.msc) to take a look at all your local drives and verify the drives returned via WMI.

Kind regards,
Johannes Beyerlein, Technical Support Team
